Portable power source
Technical field
The utility model relates to a kind of electric equipment products, relates in particular to a kind of portable power source.
Background technology
At present, development along with telecommunications industry, the personal digital articles for use such as mobile phone are used very general in people's live and work, bring great convenience for people's live and work, and the personal digital articles for use such as mobile phone need to charge with charger in use for some time.Now charger by: housing, be arranged on rotation pin, the USB interface on the housing and the control circuit board that is arranged in the housing forms.During charging, the digital articles for use such as mobile phone are connected with the USB interface of charger by connecting line, and the rotation pin of charger is connected with 220 volts of AC power.Existing charger itself only has charge function, does not have storage function, is not having in the situation of AC power, and inconvenience is charged to personal digital articles for use such as mobile phones, uses very inconvenient.
The utility model content
In order to solve the deficiencies in the prior art, the utility model provides a kind of portable power source easy to use.
In order to address the above problem, the utility model is achieved through the following technical solutions:
Portable power source of the present utility model, comprise housing, be provided with storage battery and control circuit board in the housing, the side of described housing is provided with a USB output interface, the 2nd USB output interface and Micro input interface, the surface of described housing is provided with four battery capacity indication lamps and mains switch, and a USB output interface, the 2nd USB output interface, Micro input interface, battery capacity indication lamp and mains switch all are electrically connected with described control circuit board.
Further, described storage battery adopts the 4.2V polymer battery, and battery capacity is 6600mAh.
Further, the output voltage of a described USB output interface, the 2nd USB output interface is 5V, can charge simultaneously, and a USB output interface load is 1500mA, and a USB output interface load is 500mA, output total current 2000mA.
Compared with prior art; the beneficial effects of the utility model are: 1, the output voltage of a USB output interface, the 2nd USB output interface is 5V; can charge simultaneously; the one USB output interface load is 1500mA; the one USB output interface load is 500mA; output total current 2000mA, as accessing simultaneously two loads that surpass 2000mA, portable power source can be because of the overcurrent protection autoshutdown.When 2, charging, 4 LED battery capacity indication lamps show corresponding battery electric quantities.3, adopt USB port power supply output, plug and play is plugged data wire and is namely realized with oneself, charges at any time.4, can use to all equipment with the USB charging, such as panel computer, learning machine, mobile phone, PSP, iPhone, MP4, PMP, GPS, the bluetooth digital camera, etc., compatible most of digital equipment.
Above-mentioned portable power source, when being arranged, the AC power input can charge to personal digital articles for use such as mobile phones, also can the storage battery of portable power source inside be charged simultaneously, when disconnecting AC power, the storage battery of portable power source inside can directly charge to personal digital articles for use such as mobile phones, and is very easy to use.

Embodiment
Below in conjunction with drawings and Examples, embodiment of the present utility model is described in further detail.Following examples are used for explanation the utility model, but are not used for limiting scope of the present utility model.
As shown in Figure 1, a kind of portable power source, comprise housing 1, be provided with storage battery and control circuit board in the housing 1, the side of described housing 1 is provided with a USB output interface 11, the 2nd USB output interface 12 and Micro input interface 13, the surface of described housing 1 is provided with four battery capacity indication lamps 14 and mains switch 15, the one USB output interfaces 11, the 2nd USB output interface 12, Micro input interface 13, battery capacity indication lamp 14 and mains switch 15 all are electrically connected with described control circuit board.
Further, described storage battery adopts the 4.2V polymer battery, and battery capacity is 6600mAh.
Further, the output voltage of a described USB output interface, the 2nd USB output interface is 5V, can charge simultaneously, and a USB output interface load is 1500mA, and a USB output interface load is 500mA, output total current 2000mA.
As shown in Figure 2, control circuit board comprises the MCU control circuit, is connected electrically in charge management circuit, booster circuit, over-charging of battery over-discharge protection circuit and the electric quantity display circuit of this MCU control circuit.
In addition, booster circuit is electrically connected with the circuit diagram shown in output USB1 module, output USB2 module, output USB1 current limit circuit, the output USB2 current limit circuit by specification accompanying drawing 2 respectively.
The operating instruction of portable power source of the present utility model is as follows:
1. press mains switch under off-mode, at this moment, the output port is opened, and the battery capacity indication lamp shows corresponding dump energy simultaneously.
2. in the situation that output port is opened, the long mains switch of pressing surpassed after 3 seconds, and output is closed.
3. after output port was opened, output port connected charging device after 30 seconds in nothing, the equipment autoshutdown.
4. when giving equipment charge, enter charged state after, export autoshutdown in the charging, keys deactivation, 4 LED battery capacity indication lamps by state of charge by flashing clockwise.
The above only is preferred implementation of the present utility model; should be understood that; for those skilled in the art; under the prerequisite that does not break away from the utility model know-why; can also make some improvement and modification, these improve and modification also should be considered as protection range of the present utility model.
